Riverview Park in Chicago was one of the great urban amusement parks, opening in 1904 at Western and Belmont avenues on the Northwest Side and closing in 1967. It featured what some insist was the finest roller coaster of all time, The Bobs. Other popular coasters were The Comet, The Silver Flash, The Fireball and The Jetstream. Aladdin's Castle was a classic fun house with a collapsing stairway, mazes and turning barrel. The former grounds are now home to Riverview Plaza shopping center, the Belmont District police station, DeVry University, a manufacturing company and Richard Clark Park, part of the Chicago Park District.
